Answer:
Shorter than(?)
Explanation:
What is it that you're looking for here? Is it just some random fill in the blank question?
My guess is that the horizontal distance has to be shorter than that of the ladder length because if it wasn't then the ladder would be laying down or maybe standing straight up... and you can't really use it normally like that... I'm sorry, where is the Physics in this question exactly?
Material composing the body,
temperature of the body and the length of the body affects the electrical
resistance of a body. Bodies directly surrounding the body will not affect the
electrical resistance of the body. The answer is letter D.
<span>Lead (Pb) is used to shield people from radioactive substances. Due to its high density and high atomic number, it is effective at reducing the effect of some kinds of radiation, including gamma rays. It can either be worn by a person or it can case the equipment.</span>
No, not exactly. They jiggle and tremble and vibrate a lot, but
they always basically stay in very nearly the same place.
It's like if you're allowed to go anywhere you want in your jail cell,
you wouldn't exactly call that "moving about freely".
Answer:
Since S (displacement) = v * t
you can calculate the area under the graph
S = 1/2 * 3 * 15 - 3 * 13 = 22.5 - 39 = -16.5 m
In the triangular area the object travels at an average speed of 7.5 m/s
for 3 sec = 22.5 m
In the rectangular area the object travels at an average speed of -3 m/s
for 13 sec = -39 m.
So the net distance traveled is 22.5 - 39 = -16.5 m
